Hi Damaraq

That's a toughie. What a great company you must work for! Is it kind of a buffet style lunch or is there only one option?

If there is a choice, you could just go with any low carb options such as meat or veges, and take some extra food from home to supplement if it is not enough.

If they only have one choice and it is high carb then you are probably doing the best thing by bringing your own.

You could always approach the chef and ask if s/he would mind doing a low carb dish each day.

As for explaining to your colleagues, I generally tell people I am cutting out all sugars and white starchy foods....seems to work mostly

Good luck!
